Traffic is queueing on the M25 either side of the Dartford Crossing after a vehicle stalled inside the tunnel and a crash closed lanes on the motorway.
Traffic monitor Inrix was reporting a ten-mile tailback on the M25 at 10.15am on Tuesday due to the two incidents.
The stalled vehicle closed the left-hand tunnel, with traffic being diverted through the right-hand tunnel.
Meanwhile, a crash was reported a few miles south on the M25 at Junction 1b (Dartford), closing two lanes of the M25.
The two incidents have caused a huge tailback stretching about 10 miles from north of the Dartford Bridge to Swanley in Kent.
